An Inquiry into the Spontaneous Transfer of Problem-Solving Skill

Problem solving, by definition, involves achieving new understanding in unfamiliar contexts, and is critical to all aspects of life, especially in the educational and scientific arenas. Students learn from many experiences to develop a repertoire of abilities, including the use of logic, which enable them to spontaneously transfer their problem-solving skill to unfamiliar situations. The purpose of this study is to explore the minimum conditions necessary to facilitate the spontaneous transfer of problem solving skill in an unfamiliar context. One hundred and seventy-five subjects were presented with logically identical problems based on the Wason selection task, which differed only in the degree to which a familiar schema could be invoked to help solve the problem. In the pretest stage, only 10.5% of subjects could solve the selection problem in an unfamiliar context, whereas 57.3% could solve it in one that was familiar. The effect of three interventions, prior exposure to a familiar scenario, repeat opportunities on like problems, and process-oriented feedback, on selection task performance in an unfamiliar context was assessed in a posttest stage. Overall, none of the interventions were effective, indicating that the minimum threshold for spontaneous transfer may be above the level of intervention included in this study. Schema theory, implications for instruction, and directions for future research are discussed.     

At the heart of child care: Predictors of teacher sensitivity in center-based child care

This study examined the extent to which characteristics of early childhood teachers and settings predicted observed teacher sensitivity. Participants included 41 head teachers at child care centers located in Northern California. Accreditation status, center size, and program quality were uniquely associated with teacher sensitivity. Accreditation was also associated with a number of other teacher (training, ethnic minority status, and depression) and setting characteristics (program quality, subsidies, and child ethnic minority enrollment). Other unique predictors included more teacher training, smaller center size, and perceived organizational health. Having a greater number of depressive symptoms or working in a larger center were identified as risks to teacher sensitivity, and were moderated by higher levels of teacher training and observed program quality The current study provides preliminary support for the importance of examining the ways that teacher and setting characteristics are related to teacher interactions with young children.     

ADAPTING A METHODOLOGY FROM MATHEMATICS EDUCATION RESEARCH TO CHEMISTRY EDUCATION RESEARCH: DOCUMENTING COLLECTIVE ACTIVITY

In this report, we adapt and extend a methodology for documenting the collective production of meaning in a classroom community. A cornerstone of the methodological approach that we develop is a close examination of classroom discourse. Our efforts to analyze the collective production of meaning by examining classroom interaction are compatible with the relatively recent emphasis in mathematics and science education research that focuses on how communities of learners establish ideas through discourse and inquiry. The methodological approach we take builds on and extends an approach from mathematics education that uses Toulmin’s argumentation model to document and analyze students’ conceptual progress. Our modification introduces a new criterion for empirically demonstrating when particular ways of reasoning become part of the normative practices of the community. An example from an undergraduate course in physical chemistry is used to illustrate the methodology.
